| Title: |
Pipe Glycol Dehydrator Vapor to VRU. |
| Text: |
Table 1â€"Cost-Effective Options for Reducing Methane Emissions: "Pipe Glycol Dehydrator Vapor to VRU. Another option for reducing methane, VOC, and HAP emissions from a glycol dehydrator is to pipe the regenerator vent stack to an oil-storage tank equipped with a vapor-recovery unit (VRU). The vapor space in the tank serves as a cushion for variations in pressure and flow from the dehydrator and oil production. Additional gas recovery enhances the economics of a VRU. The VRU boosts the recovered gas pressure enough to inject it into a fuel-gas system, compressor-suction, or gathering/sales line."
